Twin DNA Testing

EasyDNA offers the possibility to carry out an accurate twin DNA test. It is important to bear in mind that basing one’s classification of twins as either fraternal (heterozygotic twins) or identical (monozygotic twins) on appearance is an unreliable and misleading technique.

EasyDNA offers twin DNA testing with reliability and professionalism which will determine whether the twins in question are identical or fraternal. Identical genetic profiles indicate a clear case of identical twins, whilst dissimilar genetic profiles confirms the twins are fraternal.

Reasons for doing a twin zygosity test

To satisfy their curiosity both parents of twins and twins themselves might be inclined towards knowing whether they are fraternal or identical twins. However, knowing for medical/health reasons is also important. In the case of the need for blood transfusions or organ donation, identical twins can donate blood to each other and moreover make more suitable organ donors. The chances of an organ being rejected are far lower when identical twins donate organs to each other.

Twin DNA test sample collection

Sample collection for our twin DNA test is simple and straightforward. Once you have made your order, we will send out your kit. Kits contain buccal swabs for DNA sample collection, instructions, consent forms and a pre-addressed envelope. Swabs need to be rubbed inside the mouth for ten seconds in order to collect samples. We will need DNA samples from both twins.

The consent forms need to be signed by all people who have submitted samples. If twins tested are under the age of consent any parent or guardian can sign on their behalf. Once all samples have been collected and forms filled in, send everything back to the laboratory for testing, Our twin DNA test results are 100% accurate.
